bracket 5 which is in turn piirotally connected, as by pivot pin 6, with the lower end portions of the-legs 2. A tension spring 7 is pivoted about the pin 6 and has one of its ends engaging a stop 8 carried by the legs 2 and its other end bearing upon the bracket 5 so as normally to swing the bladein a contra-clockwise direction.

The operating handle, as H, is pivotally mounted upon a pivot pin 9 which is carried by the legs 2 and projects upwardly through an opening 10 formed through the base 1, and through formed through the wall 1 of the box.

A link 12 'is pivotally mounted upon the pin 9 and a second link 13 is mounted 'upon.

a pivot pin/14 carried by the bracket 5 and the links 12 and 13 are pivotally connected together by a pivot pin 16 so as to form a tpggle for controlling the movements of the Switchblade in response to the movements of the operating handle. The link 12 is provided with an extensionl't' for engaging an under-surface portion of the base 1 to limit movement of the toggle in broken position, as in Fig. 1, and an extension 18 is formed upon said link 12 to engage another under-surface portion of the base 1 to limitmovement of the toggle in straightened position, as shown in Fig. 4.

The operating handle H is-formed with a pair Of shoulders 19 and 20 at its inner end, said shoulders being'spaced apart anddisposed for engaging against the upper end of the link 13, that is at the knee of the toggle, for moving the toggle from one po sition to another. When the parts are in and a movement of the operating handle toward the left will press the knee downwardly and into the position shown in Fig. A light spring 21 is carried by the pivot pin 9 and is arranged for urging the operating handle normally into its on position. This spring however is of considerably less strength than the spring '7 so as not to interfere with the function of said spring 7. The spring 21 serves principally to retain the operating handle in a normal position against loose play movements.

' To move the parts from the position of F 4 backwardly into the off position; the handle r wung to the right so as to move the shoulder 19 away from the tow ie knee and to then bring the shoulder 20 net the knee from the opposite direction. By the tiny. the shoulder 20 moves the knee hast renter the shoulder 19 will have reached substantially the extrem of its backward movement so that as the knee snaps over into toggle breaking position the shoulder 1 will have nine to rest and the force of the blow wi. be taken up by the extension a registering opening 11' by the reference numeral 22. In the structure illustrated it is in the form of a plunger conne cted to the pivot pin It; by its innor end and being slidably supported and retained in position bya guide rod 23 mounted upon the legs 2 and engaging with in a slot 24 formed in the plun; at each movement of the toggle t plunger is operated either outwardly or inwardly r so that according as the toggle is straightened or broken. A plunger of this character may be eiiect-ually used for controlling door lock ingr mechanism, or for constituting aware: to prevent detachment of the su 5th mcchm 'nism, or for controlling other switch unchanisms and etc, as eh m in ny roperuliug applications Serial Nos. -:..l;16--158.957- 158,958--158,960, also for ier uses as will suggest themselves.

For convenience and efficiency in manufacture this plunger 22 is preferably made" up with a pair of legs as 25 spaced apart to receive the toggle links and the operating handle between them, a connecting plate 26 being arranged to connect the outer ends of the parts 25 together. This plate 26 may serve as a bumper in certain instances if desired. Suitable collars 27 may be mounted upon the guide rod 23 to retain the plunger centered, as clearly indicated in Fig. 3. As clearly shown in Figs. 1, 4 and 5 the pivotal mounting 16 for the switch blade is arranged nearer to the end 28 ot the switch blade than to the end 29, also that the flexible metallic plates 30 "forming the switch blade project at greater length beyond the ends 31 of the stifi'ening elements 32 than beyond the end of thestifl'ening element 3 1. By this means a greater degree of flexibility is given to the end 29 than to the end 28.

The result of this arrangement is graphically illustrated in Fig. 5 which illustrates the position of theends of the switch blade relatively to the two contacts 35 and 36 at the moment following the breaking of engagement with one of said contacts. It will be seen that although the end 28 of the switch blade has already left the contact 35 still the end 29 of the blade remains in engagement with the contact 36. Any spark or arc which may follow breaking of the circuit is localized-between the end 28 and the contact as there will be no current wow and, Lemme; motor t 3o. ifting; vomont omh :2: tho om:
